I have an '06 Liberty with the 3.7 in it. I have had the worst luck with this vehicle. Bough it used from dealer in October '16 and the original engine died in December. It had overheated from the water pump dying in the middle of DC traffic. *****.
Dealer took pity on me, replaced it with a junk yard engine, while eating 2/3 of the cost. In March that engine died. It had a tap, like a cylinder misfire, dealer said it needed a new engine, so second junk yard swap out. Keep count, that is 3 engines in this Jeep within 3 months (original, swapped, and swapped again).
Here we are in July, and engine problems again. I though my exhaust had backed off the manifold, no luck. Have a loud metal knocking sound at idle coming from the front of the engine, so I am assuming that it's timing chain/guides/tensioners.
Rather than go back to dealer and have them tell me to swap the engine again I figured I'd try to fix this one myself. I'm pretty handy and from what I've read/watched on youtube it seems like this is the job:
1. Pull valve covers
2. Align crankshaft to TDC
3. Remove belt
4. Remove crankshaft pulley
5. Remove timing cover
6. Remove chains and old guides/tensioners
7. Replace guides/tensioners
8. Replace chains
9. Bolt cover back on with RTP grey
10. Put Pulley, then belt, back on
11. Put valve covers back on
12. Problem solved
So my question: Do I have the steps right? Assuming I know how to turn a wrench, is this a 1 day job? Is there anything I should look for? Advice?
